Hierarchical Synchrony of Phase Oscillators in Modular Networks
Per Sebastian Skardal, Juan G. Restrepo
We study synchronization of sinusoidally coupled phase oscillators on networks with modular structure and a large number of oscillators in each community. Of particular interest is…
Unidirectional Pinning and Hysteresis of Spatially Discordant Alternans in Cardiac Tissue
Per Sebastian Skardal, Alain Karma, Juan G. Restrepo
Spatially discordant alternans is a widely observed pattern of voltage and calcium signals in cardiac tissue that can precipitate lethal cardiac arrhythmia. Using spatially coupled…
Stochastic Ordering based Carrier-to-Interference Ratio Analysis for the Shotgun Cellular Systems
Prasanna Madhusudhanan, Juan G. Restrepo, Youjian +3
A simple analytical tool based on stochastic ordering is developed to compare the distributions of carrier-to-interference ratio at the mobile station of two cellular systems where…
Multi-tier Network Performance Analysis using a Shotgun Cellular System
Prasanna Madhusudhanan, Juan G. Restrepo, Youjian +3
This paper studies the carrier-to-interference ratio (CIR) and carrier-to-interference-plus-noise ratio (CINR) performance at the mobile station (MS) within a multi-tier network co…
Cluster Synchrony in Systems of Coupled Phase Oscillators with Higher-Order Coupling
Per Sebastian Skardal, Edward Ott, Juan G. Restrepo
We study the phenomenon of cluster synchrony that occurs in ensembles of coupled phase oscillators when higher-order modes dominate the coupling between oscillators. For the first…
A network-specific approach to percolation in networks with bidirectional links
Dane Taylor, Juan G. Restrepo
Methods for determining the percolation threshold usually study the behavior of network ensembles and are often restricted to a particular type of probabilistic node/link removal s…
